Details about how Aquaman and the Flash will be introduced in “Batman v. Superman: Dawn of Justice” have leaked online. The scene descriptions reveal how one of the main characters in the movie comes to know about Aquaman and his whereabouts. [Spoiler alert]

Jason Momoa will play Aquaman in the forthcoming movie. Heroic Hollywood reports that the character will be held prisoner in a containment chamber that may belong to Lex Luthor, played by Jesse Eisenberg. The character is said to be discovered by Batman when he breaks into Lexcorp.

According to the report, one scene shows Batman accessing the company's security-camera footage. The video apparently shows the containment chamber of Aquaman and the viewers will get to see Momoa’s hand slap against the glass of the chamber.

The footage also shows the Flash (Ezra Miller) stopping a robbery. While director Zack Snyder has confirmed Momoa’s appearance in “Batman v. Superman: Dawn of Justice,” there has still been no official confirmation about the Flash being in the movie.

According to the report, details about how and why Aquaman ends up in the containment chamber may be revealed in “Suicide Squad,” which is set to arrive in August 2016. Snyder’s movie will be released in March 2016.

Another report by Heroic Hollywood says that Aquaman and the Flash will only make cameo appearances in Snyder’s movie. The report also reveals that the robbery that Miller’s character will be stopping will be at a bank. The video footage supposedly shows the character to be a “blur.”

Unlike the Marvel movies, which take a “linear” approach to establishing new characters, the report states that DC will choose an “established universe” route. So viewers will not get an origin story for some of the characters in “Batman v. Superman: Dawn of Justice.”
